They were soon in full sight of the fort and the redskins clamoring about it. And it was a complete surprise to Oak Heart and his braves to see reenforcements for the whites so near at hand. As for the defenders of Fort Advance, they were wild with joy to see even this small troop coming to their rescue.

Buffalo Bill’s white steed was recognized, and cheers rent the air from the garrison which, a few moments before, had given up all hope. The Indians had been about to rush the stockade, and then a hand-to-hand fight would have ensued inside the fort which could have ended in but one way. The redskins outnumbered the whites so greatly, despite their losses, that the garrison would have been completely overwhelmed.

Oak Heart saw that he was likely to be defeated, after all. Victory had all but perched upon his banners; now, with his forces separated, he was very likely to taste the bitter ashes of defeat!

But the Sioux king was a born leader and strategist. He saw that, in some way, his plans for ambuscading the relief party had fallen through. His three hundred braves were idle up the cañon while the whites from Fort Resistence were coming to the help of their comrades by another way. Those reserve forces he needed, and needed at once.

He spoke to the White Antelope. She had acted as his aid all through the battle, and now she wheeled her pony instantly and dashed away toward the mouth of the cañon. She was instructed to inform the ambuscading party of the change in affairs and to bring them back at top speed.

Buffalo Bill and his flying column of cavalry saw and understood this move. Lieutenant Dick Danforth, the dashing young lieutenant who ranked in command of the party, spurred up beside Cody.

“See that girl yonder?” he cried.

“I see her,” returned the scout gravely.

“She’s a messenger, eh?”

“She is.”
